Functions of graphic equalizerCompensation for the audio characteristics of the listening room
The listening room may contain several objects. Some of them reflect sound and some absorb sound , thus the sound reaching your ears is considerably affected by these objects.
In such cases, the graphic equalizer can be used to adjust the frequency response of the room for a flat response from low to high frequencies.
¶Low frequencies are absorbed by beds, chairs, etc. ¶High frequencies are absorbed by curtains, screens,
etc.
¶The room structure can cause the low frequencies to be unclear, or the sound level to increase or decrease depending on the frequency.

Super bass range (40 Hz ~ 63 Hz)
When this control is moved up, the bass instrument (double bass, bass drums, or pipe organ, etc.) sound is increased.
When the super bass sound is boomy, move this control down.
Bass range (98 Hz ~ 160 Hz)
Usually, the listening room resonance frequency is in this range. To eliminate bass resonance, move this control down.
This range is the basis of music. Whether the sound is rich or not, depends on this range. When the playback sound is not so good, move this control up.
Mid range (625 Hz ~1 kHz)
This range is related to stimulus and metallic sound. When this range is well compensated, vivid sound can be obtained.
High range (3.9 kHz ~ 6.3 kHz)
This frequency range is related to the hardness of the sound. When this control is moved up, strings or brass instruments, such as flutes or piccolos, are emphasized. When the control is moved down, the sound will be more soothing.
Super high range (10 kHz ~ 16 kHz)
This frequency range is related to the details of the music. When this control is moved up, super high frequency instruments, such as triangles or cymbals, are emphasized, resulting in wide sound and echoes.
When this control is moved up or down, the baritone or soprano voice is
